From mboxrd@z Thu Jan 1 00:00:00 1970 From: Pablo Neira Ayuso Subject: [PATCH 0/9] Netfilter fixes for net Date: Mon, 28 Mar 2016 19:57:53 +0200 Message-ID: <1459187882-5357-1-git-send-email-pablo@netfilter.org> Cc: davem@davemloft.net, netdev@vger.kernel.org To: netfilter-devel@vger.kernel.org Return-path: Sender: netdev-owner@vger.kernel.org List-Id: netfilter-devel.vger.kernel.org Hi David, The following patchset contains Netfilter fixes for you net tree, they are: 1) There was a race condition between parallel save/swap and delete, which resulted a kernel crash due to the increase ref for save, swap, wrong ref decrease operations. Reported and fixed by Vishwanath Pai. 2) OVS should call into CT NAT for packets of new expected connections only when the conntrack state is persisted with the 'commit' option to the OVS CT action. From Jarno Rajahalme. 3) Resolve kconfig dependencies with new OVS NAT support. From Arnd Bergmann. 4) Early validation of entry->target_offset to make sure it doesn't take us out from the blob, from Florian Westphal. 5) Again early validation of entry->next_offset to make sure it doesn't take out from the blob, also from Florian. 6) Check that entry->target_offset is always of of sizeof(struct xt_entry) for unconditional entries, when checking both from check_underflow() and when checking for loops in mark_source_chains(), again from Florian. 7) Fix inconsistent behaviour in nfnetlink_queue when NFQA_CFG_F_FAIL_OPEN is set and netlink_unicast() fails due to buffer overrun, we have to reinject the packet as the user expects. 8) Enforce nul-terminated table names from getsockopt GET_ENTRIES requests. 9) Don't assume skb->sk is set from nft_bridge_reject and synproxy, this fixes a recent update of the code to namespaceify ip_default_ttl, patch from Liping Zhang. This batch comes with four patches to validate x_tables blobs coming from userspace. CONFIG_USERNS exposes the x_tables interface to unpriviledged users and to be honest this interface never received the attention for this move away from the CAP_NET_ADMIN domain. Florian is working on another round with more patches with more sanity checks, so expect a bit more Netfilter fixes in this development cycle than usual.
